Protohackers in Elixir: day 0 - Setup and Smoke Test

Andrea Leopardi sets up an Elixir project and implements a basic TCP smoke test server for the Protohackers challenges.

This is the first video of a series on solving some network programming challenges in Elixir elixir-lang.org. The challenges are from protohackers.com. I’m deploying code using a free account on fly.io. The source code is on GitHub: github.com/whatyouhide/protohackers_in_elixir Some resources for the video: • Basics of #TCP: youtube.com/watch?v=8-32WcWDiOA • Deploying #elixir applications on Fly.io: fly.io/docs/elixir/getting-started/legacy • Documentation for the #erlang gen_tcp module: erlang.org/doc/man/gen_tcp.html • Documentation for the Task.Supervisor Elixir module: hexdocs.pm/elixir/Task.Supervisor.html Other resources: • My website: andrealeopardi.com • Twitter: twitter.com/whatyouhide • Mastodon: mas.to/@whatyouhide Music from Uppbeat (free for Creators!): [uppbeat.io/t/walz/name](uppbeat.io/t/walz/name) License code: WX2ISVMMX8I1FJMDThis is the first video of a series on solving some network programming challenges in Elixir ([elixir-lang.org](elixir-lang.org/)).
